如何利用列表理解获得预期的结果

Question

我有以下清单

a=[1,2,3]
b=[4,5,6]
c=[a,b]

我需要把a表和b表合并起来

结果应该是[1,2,3,4,5,6]

我试着理解列表

[x for x in i for i in c]

输出

[3, 3, 4, 4, 5, 5]

如何使用列表理解获得[1,2,3,4,5,6]结果。你知道吗

Answer 1

你可以这样做：

a + b

如果必须使用列表理解：

In [10]: a = [1, 2, 3]

In [11]: b = [4, 5, 6]

In [12]: c = [a, b]

In [13]: [j for i in c for j in i]
Out[13]: [1, 2, 3, 4, 5, 6]
